l'lig. 16 is a diagrammatic sectional elevation oit'n former or device:Eor lightly rolling or extending a clot of dough. In carrying out theinvention a ocording to one mode a molding machine of the type describedin the specification of United 0 ites Letters Patent No. 1,l7l,2h l isfitted .Vltll a preliminary shaper 36 comprising two oppos molded" orworked piece from the molding? machine is rolled into a substan tiallycylindrical form. This machine and preliminary shaper 36 are mounted ona :niother combination of apparatus suit? d endless bands 37, 38, drivenin directions at diiterent speeds Where tahie preferably torrningthe topof a prom l ing apparatus, comprising a casing 1' of Wood or othersuitable material and preferably in two detachable sections 2,3, so asto facilitate passage through narrow door-Ways when being as: rnbled ina baker], the selfcontained sections being joined along the center inany convenient manner.

Tillie casing contains two sets of tracks, there being oneset in eachsection comprisl1 spaced boards or rails 4;, 4, and'5, 5. rails -l, e,are horizontal While the. rails areinclined. The rails a, 4, may also"inclined itt desh'ed.- The tracks form a .l'cs for carriers 6 of anysuitable form to suit the material to be carried. They may be in theform oi buckets as indicated in l to 3, or may simply comprise plates orba es 7 provided ulth pins 8' as inin place by airelastic ring 13 orotherwise secured. The linings can be removed and Washed. They "alsoassist in the removal of the dougl'i when the carriers are inverted Thecarriers are secure-dby pins, screws or otherwise to an endless'chainls, so that'they are free to swivel relatively to one another.Theehain passed around pulleys 15 supported shafts 16 at the ends of thetracks.

' .and if desired with guide pulleys Bearings 1'? on struts 18 maytake'the stress applied to the pulley shafts by the conveyer chain, andtoot-step hearings or simply metal plates may take the vertical stressof the shafts. The pulleys may be sprocket Wheels or similar to thepulleys oi chain pulley-clocks according to the type of chain used. Theupper faces of the pulleys are adapted to act as guides or supports forthe ca riers as they pass around from one porti the track to another,and in order to avoid the carriers fouling the rims oi? the pulleys,thin sheet metal guides 19 may be provided. By reference to Figs. l, 5and (3 it will be seen that the trucks form a continuous substantiallyspiral or zig-r path for the conveyor within the casing, the course ofthe chain being inilicatcd by dot-and-dash lines. When the conveyor hascompleted one Zig-zag course on the rails 4t, at, 5 5, of one set in onesection ofthecasing it p ses across to the set in the other l lCllCfiiBdin Fig. T. In the first s section 1 p or front set the carriersgradually descend from the upper part of the casing to the lower,whereas in the other or rear set they gradual y ascend to the topemerging finally through a hole 20 Fig. 2 in the top. Here an inclinedtrack :21 leads t-h up to u pulley then o a looped trace- 23. and thencedown and into the casing' again on to the first or front set of tracles.The looped truck provided is \yith'a vertical pulley or sprocket Wheel24 at the pass over head of the loop. As tie carriers these pulleys theyare i1 yerted and dis" charge their contents. In order to retain them onthe tracl: While inverted and while they are passing down the returncurve 26, retaining flanges 2-7 oi metal or other matcrial are provided.

The sh: it 28 cl thepulleys 2t. 25, may form the driving shaft of theconveyen any suitable driving mech in being used. if desired the shafts16 may also be driven so as to better distribute the stress on thechain, for example all the shafts may be i terconnected by chain. belt,or toothed ge ng in anyivell known manner. -The driving mechanismadopted may he 'irranged to give 0. continuous feeding motion or anintermittent motion.

A guard in the form oi? a band 30 o fabric hey prevent the dough fallingon oi the carriers prematurely and may l 5 is u: to direct them on to acom r 31 or on to any 'll henever a piece of dough is Altertraveling ina circuitous manner in the casing 1 the conveyor rises up an inclinedtrack .41 around a pulley and thence over a looped portion of track 23and back into the casing 1. reyer passes around the end or" the loopedportion of tract: the carri rs 6 are in verted to discharge theircontents. By way of QXttHlPlO the conveyer indicated in Fig. l is drivenby the rotation a sprocket Wheel or pulley over which tie chain pases,'uide pulleys being arranged on the same shaft 28 as the sprocket wheel.Pieces of dough to be treated are placed on aconveyer 31 by which theyare fed to the inolder 35 by which they are coiled under tension for thepurpose set forth in specilication h o. 1,1?9Q9 i, and are then passedthrough the shaper by which they are shaped with a rolling action asdescribed in specification No. 1,169372. The fiat bands and 38 or thesharper 36 arranged in between flutside plates 39, impart a neatcylindrical shape to the pieces of molded dough which as they aredelivered, tall throng casn g ing.

Sue end of the Bowdenwire is connected by a link 59 tot-he lower dough strikes the plate a0,Fig. i, and moves the lever ll. the wire 42 pulls the trip lever 55.This causes the trip lever to move away from the pawl 52 which, engageswith the continuously moving ratchet wheel i9, so that the diskblv andtherefore the shaft 50 is rotated and by means of a pinion 6.5 and awheel 66 rotates the shaft 28, suiiiciently to drive the conveyorforward by an amount equal to the pitch oi the carriers. The disk 51only makes one revolution to etiect this movement, the gear ratio beingarranged to suit. hen the disk corn pletes a revolution, the projectionrides up the projection 5st on the trip lever which has in the meantimeretnrne zd to its osition of rest a ainst the stop 63. The P e i pawl 52is thereupon disengaged 'irom the through the niolder, preliminaryshaper and into the prover, the latter can then be run to discharge theproved pieces of dough, which can be passed by any suitable means, notshown in Figs. 1 to 3, to a cottage or other shaper according to thepeculiar shape required for the loaves, a simple form of cottage shaperbeing one or the known type comprising a shaped roller rotating within ashaped casing. Should a second molding and a cylindrical shaping bedesired, however, thepieces of dough delivered by the prover may beallowed to -fall on the conveyer 31, Figs. 1 to 3, and bedeliveredthereby to the molder and shaper 36, the opening 29 in the top of thecasing being closed by a suitable cover. It may be pre ferred tocontinuously ieed pieces of dough to the inolder 35, shaper 36, proverand thence to a cottage or other shaper. In such case an arrangementsuchas diagrammatically indicated in Figs. 13 and 14 may be used. Herethe pieces of dough placed on the conveyor 31 and after treatment by theniolder 35, shaper 86 and prover. as I above described with reference toFigs. 1 to 3, are delivered on to another conveyor 67 and by that fedinto the cottage shaper 68. Should it be desired. to cut out the cottageshaper and allow a batch to pass from the prover again on to theconveyor- 31, and thence through the molder 35 and shaper 36, therollers 69, 7 O, are wide enough to allow the conveyer 67 to be movedaside to an inoperative position, or any other arrangement may beadopted for this purpose. The combination last described will thuspermit of the continuous molding and shaping or" cottage or otherpeculiarly shaped loaves, or themaking in batches of twice molded andcylindrically shaped loaves su1table .ior what known as tin bread andsometimes as pan bread.

In lar er installations it may be desirable to work continuously whethermaking cottage or t1n bread, and in the latter caseto subject the doughto a second molding.

lt- 1s, sometin'les desirable that eac h clot or piece of dough shall.be in an elongated it'orin when fed to the molder and it may in somecases be passed through former or extender as indicated at T5 inFigs. 13and 15 instead of placing it direct on to the conveyor 31. The former 75may comprise two endless bands 76, 77, Fig. 16, running in oppositedirections at different speeds the construction being similar to that ofthe shaper 36, the bands '76, 77, however, being much wider so that theclot or piece of dough which passes, between them is elongated by thetime it is delivered on to the conveyer 31 or on to the feeding band ofthe molder 35. By presenting an elongated clot to the spindle of themolder 35 it will.
